142938 divided by 87 
We want to figure out the number of times 142938 can be divided by 87.

Going ahead to step 1:
The number 87 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 87

Moving on to step 2:
If we divide 14 by 87, we get 0 and a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 87

Moving on to step 3:
87 can be fit into 142 1 times, resulting in a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 87 from 142 and we're left with 55.
Include the next digit (9) from the dividend after 55, then repeat: 559 / 87

Step 4:
87 goes into 559 6 times with a remainder of 37.
The next digit of our result is 6. 
Result so far: 16.0
If we take 522 away from 559, we end up with 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 87

Advancing to step 5:
87 can be fit into 373 4 times, resulting in a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 164.0
If we subtract 348 from 373, we get 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 87

Advancing to step 6:
87 can be fit into 258 2 times, resulting in a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 1642.0
If we subtract 174 from 258, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 7:
87 can be fit into 840 9 times, resulting in a remainder of 57.
The next digit of our result is 9. 
Result so far: 1642.9
Deduct 783 from 840 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 8:
570 divided by 87 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 1642.96
Subtract 522 from 570 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
87 can be fit into 480 5 times, resulting in a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1642.965
Subtracting 435 from 480 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
87 can be fit into 450 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 1642.9655
If we take 435 away from 450, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 1642.9655, with a leftover of 0.00015.
